These are easy to use, just slide them in a boot. No peeling or sticking necessary and I didn't feel them move around. I work at night in a cold climate and even w/two pairs of socks my feet get cold. These were great, they didn't overheat, but they didn't last very long. However, they didn't get cold, they just lost their heat.
